Well, I apparently can't edit my first message to include the new attachment... So here it is down here in the middle of the post!

Random number generator:

Random: 
  ; See "linear-congruential random number generator" for more. 
  ; rand = (rand * 5 + 0x3611) & 0xffff; 
  ; return (rand >> 8) & 0xff; 
  lda   rand_h      ; multiply by 5 
  sta   rand_temp
  lda   rand_l 
  asl   a           ; rand = rand * 4 + rand 
  rol   rand_temp
  asl   a 
  rol   rand_temp
  clc 
  adc   rand_l 
  pha 
  lda   rand_temp
  adc   rand_h 
  sta   rand_h 
  pla               ; rand = rand + 0x3611 
  clc 
  adc   #$11 
  sta   rand_l 
  lda   rand_h 
  adc   #$36 
  sta   rand_h 
  rts               ; return high 8 bits

You need the variables rand_temp, rand_h, and rand_l to be somewhere in ram. The sequence will always be the same with a given seed, so usually games will do something like run a counter and use that as a seed when the player hits the first button.

I like FCE Ultra for an emulator myself.

You'll need a NES emulator such as Nestopia. Sounds like your catching on quickly Sivak, have fun!

I now have got a computer AI in that'll always beat you if you make a wrong move. That was the next big step. All I really need to do now is add in a random number generator and some music and some credits and we may have a final game.

Alright. I wanted to get some thoughts on things so I'm posting a demo of the game.

This version is upgraded quite a bit. It has a working AI to play against and will always beat you if you make a wrong move. If you make a right move, it's a little obvious right now, but that should change when I get randomization in there.

So what do y'all think? Go down to message #6 for the attachment....
